SMSQL 64 bit with a 32 bit database

I have a Windows 2003, 3 node MS cluster which hosts our SQL 2005 SP3 32 bit production database. A new very high spec server has been purchased which will run Windows 2003 64 bit with SQL server 64 bit Ed. The plan is to disconnect the luns from the old cluster a connect them to the new server.

Has anyone done this before and does SMSQL accept this configuration?

Thanks

Brendon

PS - Will try and test this config on Friday but would like to know this is not a 1st...
